GEAR FOR METERED FEED OF POWDER MATERIAL

摘要

FIELD: coating plants. SUBSTANCE: gear for metered feed of powder material has hopper, unit injecting transportation gas and unit removing gas and powder mixture placed coaxially and vibrator mounted on hopper. Unit injecting transportation gas is mounted for axial movement. Bottom of hopper has spherical surface and through hole which diameter is chosen depending on diameter of grains of powder material by formula described in claim. EFFECT: increased accuracy of consumption of powder material with minimal usage of transportation gas. 1 dwg
